[0021] The utility model discloses a semi-rigid suspension balance beam for a bulldozer, comprising a balance beam body 101, two oil cups 102 and two damping assemblies, wherein the balance beam body 101 has two traveling frame assembly shaft holes 103 and a frame assembly shaft hole 104, and the damping assembly comprises a slide rail 105, a slider 106, two fixed rails 107, two positioning members 108, an assembly frame 109, two fixing members 110, a plug-in member 111 and a damping member 112, wherein the fixed rail has a plurality of locking holes 121, and the positioning member 108 comprises a fixing block 113 and a The locking screw 114, the fixing part 110 includes a locking screw 115 and a knob 116, the connector 111 includes a connecting plate 117 and a socket 118, and the shock absorbing part 112 includes an elastic layer 119 and a rubber shock absorbing block 120. The above scheme solves the problem that the existing semi-rigid suspension balance beam of the bulldozer is fixed on the balance beam body 101, and therefore the position of the rubber shock absorbing block 120 cannot be adjusted according to different models of bulldozers, thereby affecting the contact area with the bulldozer and reducing the shock absorbing effect.

[0022] For this specific embodiment, the balance beam body 101 is assembled between the walking frames of the bulldozer and connected to the frame through the two walking frame assembly shaft holes 103 and the frame assembly shaft holes 104. The two oil cups 102 are used to lubricate the two walking frame assembly shaft holes 103. The specific structure and usage of the balance beam body 101 and the two oil cups 102 are referred to the patent document with publication number CN205205896U, and no further details are given here.

[0023] Among them, the slide rail 105 is fixedly connected to the balance beam body 101 and is located on one side of the balance beam body 101; the slider 106 is fixedly connected to the slide rail 105 and is located on one side of the slide rail 105; the two fixed rails 107 are respectively fixedly connected to the balance beam body 101 and are respectively located on both sides of the balance beam body 101 close to the slide rail 105; the fixed rail 107 has a plurality of locking holes 121, and the plurality of locking holes 121 are respectively located on one side of the fixed rail 107; the two positioning members 108 are respectively arranged on both sides of the slider 106; the assembly frame 109 is fixedly connected to the slider 106 and is located on one side of the slider 106; the two fixing members 110 are respectively arranged on both sides of the assembly frame 109; the plug-in member 111 is located on one side of the assembly frame 109; the shock absorbing member 112 is arranged on one side of the plug-in member 111,

[0024] Secondly, the fixing block 113 is fixedly connected to the slider 106 and is located on one side of the slider 106; the locking screw 114 is threadedly connected to the fixing block 113 and is located on one side of the fixing block 113. When the slider 106 is moved to a suitable position, the locking screw 114 on the fixing block 113 is twisted to threadably connect with the corresponding locking hole 121 on the fixing rail 107, thereby completing the fixing of the position of the slider 106.

[0025] Again, the locking screw 115 is threadedly connected to the assembly frame 109 and is located on one side of the assembly frame 109; the knob 116 is fixedly connected to the locking screw 115 and is located on one side of the locking screw 115. When the connector 111 is inserted into the assembly frame 109, the knob 116 is twisted so that the locking screw 115 is threadedly connected to the connector 111, and the assembly of the shock absorber 112 is completed.
